Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 426 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 426
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A developer is building a microservice that uses AWS Lambda to process messages from an Amazon Simple Queue Service (Amazon SQS) standard queue. The Lambda function calls external APIs to enrich the SQS message data before loading the data into an Amazon Redshift data warehouse. The SQS queue must handle a maximum of 1,000 messages per second.

During initial testing, the Lambda function repeatedly inserted duplicate data into the Amazon Redshift table. The duplicate data led to a problem with data analysis. All duplicate messages were submitted to the queue within 1 minute of each other.

How should the developer resolve this issue?

  • A. Create an SQS FIFO queue. Enable message deduplication on the SQS FIFO queue.
  • B. Reduce the maximum Lambda concurrency that the SQS queue can invoke.
  • C. Use Lambda's temporary storage to keep track of processed message identifiers
  • D. Configure a message group ID for every sent message. Enable message deduplication on the SQS standard queue.
